3. Double Block & Bleed Valves
Why YDB Double Block and Bleed Valves Are
Preferred by Customers?
Double block and bleed (DBB) valves provide a single valve that
can simultaneously cut off/isolate the downstream and
upstream systems. In the block and bleed configuration, needle
valves or ball valves are used as drain valves or bleed valves
while ball valves are used as isolation or block valves.
Double block and bleed valves provide positive shut-off and
zero leakage which makes them ideal for product metering,
product isolation, aviation fueling, blending, tagout/lockout,
tank storage, product manifolds and other applications.
Advantages of Double Block and Bleed Valves
Double block and bleed valves are ideal for critical processes
and widely used for hazardous fluids and high pressure
systems. Applications where double block and bleed valves and
double block and bleed ball valves are used include gauge
isolation, chemical seal isolation, chemical injection connection,
chemical instrument isolation, direct mounting of instruments,

4. sample connection, gauge isolation remote mounting of
instruments and instrumentation drain.
